The figure below shows the variation of the magnetic flux linkage with time, t, for a small generator b) The generator has a flat coil that is rotated at a steady frequency in a uniform magnetic field. The coil has 900 turns and a cross sectional area of 1.5 x 103 m². The output from the generator is connected to a resistor of resistance 450 2. The value of the maximum flux linkage ( Nomar) is 20 x 10-3 Wb-tums. The times when the flux through the coil changes direction are: t₁ = 2.5ms. t₂ = 7.5ms. t3 12.5ms and t₁ = 17.5ms. a) c) No Magnetic Flux linkage (x10³Wb) Calculate the frequency of rotation of the coil. Round your answer to 3 significant figures. Calculate the magnetic flux density, B, of the magnetic field. Round your answer to 3 significant figures. Calculate the maximum electromotive force (emf) induced in the coil. Round your answer to 3 significant figures. d) Hence, or otherwise, calculate the maximum power dissipated in the resistor. Round your answer to 3 significant figures.
